1)750:10=75км-проехала машина в один час
2)75:5=15км -Скорость всадника в один час
Ответ:15км

Answer 2

Problem Analysis

We are given that the speed of a car is 5 times greater than the speed of a rider. The car travels a distance of 750 km in 10 hours without stopping. We need to find the speed of the rider.

Solution

Let's assume the speed of the rider is x km/h. Since the speed of the car is 5 times greater than the speed of the rider, the speed of the car is 5x km/h.

We can use the formula distance = speed × time to solve this problem. The distance traveled by the car is 750 km, and the time taken is 10 hours.

For the car: distance = speed × time 750 = (5x) × 10 750 = 50x

To find the speed of the rider, we need to solve for x in the equation 750 = 50x.

Calculation

Let's solve the equation to find the value of x:

750 = 50x

Divide both sides of the equation by 50:

750/50 = x 15 = x

Therefore, the speed of the rider is 15 km/h.

Answer

The speed of the rider is 15 km/h.
